also adapted for heating, cooling and cleaning the metal molds.

Figure I shows a cross sectional elevation of the burner taken on theplane TI of Fi re Tl.

igure II shows the application of this burner to the mechanism describedin the oo-pending application, Serial No. 633,903, filed 23 April, 1923,by myself.

In Figure I, A is the body of the burner. This burner is cored out andcontains within it the assage B. This passage is pro-' vided at with athreaded entrance which serves as a supporting means for the burner andalso as a conduit through which the combustible gas is admitted to theburner. The main casting A is also provided with a second entrance Dthrough which the cooling, cleaning and heating gases are admitted.

Outlets E are provided for the cooling, heating and cleanm gases and tothese outlets E the nozzles l? direct the cooling, heating and cleaninggases against the surface of the molds. The cored passage B connectswith the outlets G to which the nozzles H are threaded. These nozzles Hdirect the flame'of the carbon de ositing gas against the surface of themo ds. A drain plug J is provided in the casting A for removing, anymoisture that may be deposited therein from the compressed air. I

A flexible pipe K connects with the entrance Cto the casting A. A secondflexiblepipe L connects with the entrance 1). Compressed air andilluminating gas are supplied through L and acetylene is suppliedthroughK. A valve M controls the supply of illuminating gas. A valve N contro sthe supply of compressed air and the valve Q to the pipe K controls thesupply of acetylene.

are connected which ance to movement. The molds U V, which are shown inthe open position, carry a projectin arm W which contacts with the armP. T e molds U V rotate about the same center as the piece Q and the armP. The arm W therefore carries the arm P and the casting A with themolds U V.

The track R, however, is inclined so that as the molds rotate the arm Pand the casting A are raised until the arm P .clears the arm 'W, uponwhich the casting A and the arm P return to their initial positionsrunning down the inclined track R and re-engaging with the nextsucceeding molds. The mo ds U V are carried by the rotating table X uponwhich the molds U V rotate and also move into and out of engagement witheach other.

0peratz'on.-.-Immediately. prior to running the machine the valves 0 andM are closed, the valve N is opened and the molds are thoroughly cleanedby the compressed air issuing out of the nozzles F. The valve N isclosed and the valve M opened, and ordinary city gas ignited in theburners F. This gas flame is allowed to play on the molds U V until suchtime as they have reached a sufficiently high temperature,-

which is 500 or 600 F. The table X is then rotated and another pair ofmolds are heated until all the molds on the table have been heated tothe desired temperature. The valve M is thenclosed, the valve 0 isopened and the acetylene flame allowed to play-upon the molds U V, thegas issuing out of the nozzles H. The molds are thereafter coated withlam black every time the table X carr ing the molds U V rotates.

e metal molds are preferably protected with the coating described in theU. S. Pat-. ent 1,453,593, issued to Daniel H. Meloche on t e 1st ofMay, 1923.

ll prefer not to use the nozzle H for the com ressed air and I prefernot to use the nozz e T for the acetylene, for the reason that l havefound it preferable to make the nozzle H in diameter, whereas the nozdI. v EE I olSiZ'iSr L-In a combined lampblack burner,
